Cellular Energy

ATP, Photosynthesis, & Respiration

ATP -> ADP -> ATP …

Photosynthesis

• Reactants: Water, Carbon Dioxide, Light Energy
• Products: Oxygen & Glucose

​

• Light Reactions split water and produce NADPH and ATP
• Calvin Cycle synthesizes glucose from carbon in CO₂

Chloroplast

• Light energy is absorbed by chlorophyll in thylakoid membranes
• “Light-Dependent” Reactions

Photosynthesis: Light Reactions

Calvin Cycle

1. RuBisCo incorporates carbon from CO2 into organic molecule
2. Molecule reduced (gains e-) by ATP & NADPH
3. RuBP regenerated

​

6 Turns of cycle for 6-carbon glucose

Suggested Tasks

• Groups of 3-5
• Board game or stop motion video? Try a game or watch the exemplar videos.
• Photosynthesis or Respiration?
• Not sure yet? Start with ATP Canvas activities and think on it!

Glycolysis

Products per glucose:

• 2 ATP
• 2 NADH
• 2 Pyruvate
• Fuel for citric acid cycle

Citric Acid/Krebs Cycle

• 2 pyruvates = 2 cycles
• Products:
• 4 CO₂
• 6 NADH
• 2 FADH₂
• 2 ATP (GTP)

Oxidative Phosphorylation

Without Oxygen

Anaerobic Respiration: Alcoholic Fermentation

Anaerobic Respiration: Lactic Acid Fermentation

Tasks for Today:

• Join your energetics group on Canvas
• Decide if your board game/video is on photosynthesis or respiration
• Sign up for the OTHER (respiration or photosynthesis) lab with your group on the Canvas calendar

​

• Work time – Do what YOUR GROUP needs to do!

Why are leaves green?

Why do leaves change color in the fall?

Photosynthesis & Respiration Shuffle

• Sort the cards into two sets, photosynthesis or respiration
• Put the cards in order
• Sort the strips into the two categories
• Put the strips in order according to the processes

Photosynthesis Lab

Respiration Lab: Control Respirometers

Wednesday 11/30

Clean Up:

• Trash used peas & cotton
• Remove cotton using forceps
• Save plastic beads
• Rinse respirometer base and pipette (do not remove from stopper)
• Wash your hands!

Storyboard Planning

Video Planning: Storyboard

Elements of a Storyboard

• Shot images: Individual panels featuring 2D drawings to show what’s happening—actions, characters—throughout a video
• Shot number: The number indicating when a shot appears according to a video’s shot list
• Action: The primary activity happening in a shot
• Dialogue or narration: Any speech that is heard throughout a video
• FX: Any additional technical details that explain how the shot is created (e.g. camera angles, camera movement, sound effects, special effects)

Gallery Walk

Gallery Walk

• Set up your materials for other students to view
• If you have a specific question to guide feedback, write it on blue paper
• Use sticky notes to comment on other groups’ work – What you like, how they can improve, clarifying questions
